How+a+thermometer+works-Video

How a Thermometer Works-Video   I chose this video because it provides a lot of information on how a thermometer works. This explains how a liquid filled thermometer works. It is pretty straight forward but I think this man explains it well. He explains how the alcohol rises and lowers because of expansion and contraction. You may stop the video around one minute because that is the only thermometer that I used for this project.
